Phlegon, Greek historian from 80-100-? AD, writes in Olympiads>Chronicles>Book 13/14, of Jesus making certain predictions which had been fulfilled(as reported here by Origen, Alexandrian scholar from 185-254 AD, writing in Origen Against Celsus>Book 2>14): Now Phlegon, in the thirteenth or fourteenth book, I think, of his Chronicles, not only ascribed to Jesus a knowledge of future events (although falling into confusion about some things which refer to Peter, as if they referred to Jesus), but also testified that the result corresponded to His predictions. So that he also, by these very admissions regarding foreknowledge, as if against his will, expressed his opinion that the doctrines taught by the fathers of our system were not devoid of divine power.

Phlegon also writes in his chronography, (Book 13>Olympiad 202/203), of an eclipse and earthquake that took place around Jesus' crucifixion, as reported here by many other ancient scholars:

Origen, Alexandrian scholar from 185-254 AD, writes in Origen Against Celsus>Book 2>33-59: And with regard to the eclipse in the time of Tiberius Caesar, in whose reign Jesus appears to have been crucified, and the great earthquakes which then took place, Phlegon too, I think, has written in the thirteenth or fourteenth book of his Chronicles. […] Celsus […] imagines also that both the earthquake and the darkness were an invention, but regarding these, we have in the preceding pages made our defence, according to our ability, adducing the testimony of Phlegon, who relates that these events took place at the time when our Saviour suffered.

John Philoponus, Alexandrian author from 490-570 AD, writes in On the Creation of the World: Phlegon mentioned the eclipse which took place during the crucifixion of the Lord Jesus and no other [eclipse]; it is clear that he did not know from his sources about any [similar] eclipse in previous times […] and this is shown by the historical account of Tiberius Caesar.

Julius Africanus, Libyan historian from 160-240 AD, writes in History of the World>18: Phlegon records that, in the time of Tiberius Caesar, at full moon, there was a full eclipse of the sun from the sixth hour to the ninth—manifestly that one of which we speak. But what has an eclipse in common with an earthquake, the rending rocks, and the resurrection of the dead, and so great a perturbation throughout the universe?

Eusebius, Roman historian from 264-340 AD, writes in Chronicle: Indeed Phlegon, who is an excellent calculator of olympiads, also writes about this, in his 13th book writing thus: "However in the fourth year of the 202nd olympiad, an eclipse of the sun happened, greater and more excellent than any that had happened before it; at the sixth hour, day turned into dark night, so that the stars were seen in the sky, and an earthquake in Bithynia toppled many buildings of the city of Nicaea." These things the aforementioned man [says].

John Malalas, Greek chronicler from 491-578 AD, writes in Chronographia: And the sun was darkened, and there was darkness upon the world. Concerning which darkness, Phlegon, that wise Athenian, writes thus: "In the eighteenth year of the reign of Tiberius Caesar, there was a great eclipse of the sun, greater than those that had been known before: and it became night at the sixth hour of the day, so that the stars appeared."

Maximus the Confessor, Constantinople scholar from 580-662 AD, writes in Scholia: Phlegon, the Gentile chronographer, in the thirteenth book of his Chronography, at the two hundred and third olympiad, mentions this eclipse, saying that it happened in an unusual manner: but does not say in what manner. And our Africanus in the fifth book of his Chronography, and Eusebius Pamphili likewise in his Chronicle, mention the same eclipse.
